概述

Description

PMEG4005CEAX is a N-channel enhancement-mode power MOSFET from Nexperia (PMEG family). It’s designed to act as a fast, efficient switch in power-management circuits.
Key points:
- Logic-level gate: suitable for turning on with standard gate drive voltages.
- Low on-resistance and fast switching: enables high efficiency in DC-DC converters, load switches, and protection circuits.
- Moderate current handling: intended for power-switching in compact SMD applications.
- Packaging indicated by the CEAX suffix: a specific surface-mount package variant (tape-and-reel/ reel details per the datasheet).
Common applications:
- High/low-side switching in DC-DC regulators
- Load switching and power-path control
- Reverse-protection and simple switching tasks in embedded power designs
Note:
- For exact electricals (Vds, Id, Rds(on), Qgs, Vgs(th), packaging details), refer to the PMEG4005CEAX datasheet. The suffix denotes a particular package/tape/reel variant, and values vary by version.

Features

PMEG4005CEAX is a single Schottky barrier rectifier. Key features:
- Reverse voltage: 40 V; average rectified current: 5 A
- Very low forward voltage drop (≈0.45–0.55 V at 5 A) for high efficiency
- Ultrahigh-speed switching with no reverse-recovery losses
- High surge current capability for short pulses
- Low reverse leakage and rugged performance with guard-ring design
- Surface-mount DO-214AC (SMA) package
- RoHS-compliant, Pb-free; suitable for switching power supplies, polarity protection, and other high-efficiency rectification tasks
- Operating temperature typically from −55 °C to +150 °C
Note: values are typical and depend on conditions; always consult the datasheet for exact tolerances.

Package

SOT-23 (SOT-23-3) package.

Pinout

- Pin count: 3 (SOT-23-3)
- Function: P-channel enhancement-mode MOSFET (PMOS) used as a high-side switch/power pass element (Source to input, Drain to load, Gate to drive).
